I have two questions about the calculations with VdW forces (input_dft = 'vdW-DF'): 1- Is it possible to perform VdW calculations with any kind of functional? Or is it mandatory to use revPBE? 2- I generated a VdW table on two different machines (sp6 of CINECA, matrix of CASPUR). I got different numbers in the files vdW_kernel_table (sign and order of magnitude are different in many cases). Could it depend on the modules I loaded on matrix? Which are the libraries used to generate the table? Adriano
